I was trying to create a frame with WindowBuilder, but unfortunetly the right and bottom corner of the JFrame is invisible in the design show. However when I run the programm, the frame is working correctly.
I tried it on JavaSE 9.0.4 and JavaSE 1.8.0_162 aswell. But both didn't work even though some weeks ago it did when using Java 8.
There is a picture uploaded I took for showing what I tried to describe.
I hope someone can help me solving that issue.
Thank you in advance.
